CORING DEVICE.

Application filed December The present invention relates to new anduseful improvements in coring devicesof the type used for removing thecore and seeds of a .grapefruit or the like.

It is the object of this invention, among other things, to provide a.device of this character that will be economical to construct, may beeasily positioned and effective in its operation. C n

Referring to the drawings; 1n which like numerals of reference designatelike parte in the several figures;

Figures 1 and 2 are elevations of my device; and

Figure 3 is a view of the bottom thereof with "the movable blade in itsflat position.

In the practice of my invention, I employ a tubular 'cutter 10, having aknife edge 11 around the bottom thereof, and to which is secured thelower ends of the bow-shaped handle 12, by studs 20, or the like, or inany other convenient manner.

rlhe blade 14 is provided with trunnions 15, which are journaled in theopenings 13 in the lower 'end of the handle 12 adjacent to the knifeedge of the tubular cutter 10. rihe center of these openings ispreferably in the same plane as the knife edge 11. This blade has acurved portion 16 and a cutting edge 17.

After the fruit has been out transversely, a portion of which isillustrated by broken lines 18 in Figure 1, the coring device is placedupon the top thereof with the knifeL .edge 11 in contact with the pulp,the blade 14 then lying flat, substantially as shown by broken lines atthe right of Figure 3. Pressure is then applied to the handle 12 uponthe head 19 thereof and the cutter is forced downwardly through the pulpunt-il the lo wer end thereof substantially 'contacts with the inside ofthe fruit skin. At the beginning of this operation the blade 14 swingsupon its trunnions until it lies in a substantially vertical position,as shown in Figure 1.y As thus positioned, the blade and tubular cutterpass through the core and pulp.-

`When projected into the grapefruit to its fullest extent the device isrotated about its axis and the blade 14 again swings upon its trunnionsand returns to its horizontal position, substantially as shown by brokenlines in Figures 2 and 3. This movement of the blade from a vertical toa horizontal position, and vice versa, being facilitated by the curvedportion 16, which is upon one side 3, 1925. Serial No. 73,034

of the aXis of the tubular cutter. rIhis rotation of the device, whenimbedded in the grapefruit cuts off at the bottom that portion of thecore and pulp within the tubular cutter. As the device is withdrawn fromthe grapefruit the core and .seeds are removed with it, being preventedfrom falling out of the cutter by the blade 14. Thus the core and seedsof a grapefruit are completely severed and removed from the fruit at asingle operation.

During the rotation of the tubular cutter, the knife edge thereof andthe cutting edge of the blade 14 are in the same plane, this beingpermissible by reason of the relative positions of the openings 13.

Not only the shape of the handle and blade, etc., but in other ways thedetails of my invention may be varied, and therefore, I do not limitmyself to the exact construction herein shown andjdescribed, but claimallthat falls fairly within the spirit and scope of the appended claims.

Having described my invention, what I claim as new and desire to secureby Letters Patent, is

1. In a device of the character described; a tubular cutter; anda bladehaving an offset portion upon one side thereof pivotally connectedtherewith in substantially the same plane as the cutting edge of thetubu-A lar cutter.

2. In a device of the character described; atubular cutter; a handle;and a blade movably mounted so `as to vary vits position in operation bydiffering directions of pressure of the tubular cutter, irrespective ofthe position of either the cutter or handle.

3. In a device of the character described; a tubular cutter; and a bladepivotally connected therewith at substantially a right angie to the axisof the cutter', the position of the blade being in part determined bythe direction of pressure applied to the cutter.

4. In a. device of the character described; a tubular cutter; and ablade pivotally connected therewith, the blade being straight for aportion of its length and curved for another portion. Y

5. In a device of the character described; a tubular cutter; and a bladepivotally connected therewith, the blade being straight for a portion ofits'lengthand curved for another portion with a cutting .edge upon thestraightportion.

6. In a device of the charac-ter described;V

a tubular cutter; a handle connected therewith; and blade having anoffset portion upon one side thereof pivotally mounted in the handle andextending across the cutting edge ot thetubular cutter.

7. In a device. of thecharacter described; a tubular cutter; and anindependently moving blade connected therewith, the position of theblade relative to the tubular cutter being determined in part by thedirection ot the pressure upon the tubular cutter.

8, in a device ot'the character described; a tubular cutter; and anindependently moving` blade connect-ed therewith, the blade au-ftoniatically assuming aposition parallel with the open end oi thetubular cutter when a rotary pressure is applied to the tubular cutterand a pos'ion at right angles to the position just described when asubstantially straight endwise pressurel is applied to the tubularcutter. l

9. ln a device ot the character described; a tubular cutter; and a bladepivotally connected therewith, the blade being straight Afor a portionof its length and curved tor another portion, the curved portion beingupon one side of the axis of the tubular cutter.

l0. ln a device of the character described; a tubular cutter; a handle;and a blade having trunnions at the opposite ends thereof journaledwithin the handle adjacent to the tubular cutter.

Vll. ln a device of the character described; a tubular cutter; a handleconnected therewith, the ends off which project beyond the cutting edgeoiE the tubular cutter; and a blade having` trunnions atV the oppositeends thereof journaled in part in that portion oi the handle thatprojects beyond the ec ge of the tubular cutter.

1Q. ln a device ot the character described; a tubular cutter; a handle;and a blade'hav ing,` trunn'ions at the opposite ends thereof journaledwithin the handle adjacent to the tubular cutterV in such manner thatthe cutting edge of the blade may in one oit its positions occupy thesame plane as the knife edge of the tubular cutter. K

i3; In a device of the character described; a tubular cutter; and ablade pivotally cone ne'cted therewith whereby it may function in a pathsubstantially parallel with the axis ot the tubular cutter, or atsubstantially a right angle thereto, these different positions iff ot'the blade being determined in part by thev direction ot pressure appliedto the tubular cutter. y

lil. ln a device ot the character described; a tubular cutter; and ablade pivotally con nected therewith, the position of the blade being inpart determined by its contact with the material engaged thereby.

15. ln a device o1" the character described; a tubular cutter, and ablade pivotally connected therewith, said blade by reason ot its Contactwith the fruit making` a cut therein substantially parallel with theaxis of the tubular cutter while pressure is applied to the holder,substantially parallel to its airis; and a. cut substantially parallelwith the cutting edge ot the tubular cutter when the latter is movedabout its axis.
